Specification of Letters Patent.

Application filed. October 21, 1908, Serial No. 458,810;

To all whom it may concern: a

Be itknown that I, Jossrn T. Cnnwronn, a citizen of the United States of America, resi at 1611 Vine street, city and county of lhihnlelphia, and State of Pennsylvania, have invented certain new and useful improvements in Metal Rooting for Cars, of which the following is a specification.

The object of this invention is the production oi a carroofing in the form of a t of sheet metal plates. Either a part or all of the plates are suitably strengthened and when joined at their edges form a complete roof which does not require to be otherwise supported; 2'. 0., there are no bridge beams,

carlines, purlins, etc.

In the accompanying drawings ,-Figure 1 is a fragmentary vertical, longitudinal, sectional elevation of a car showing the application of my roofing. Fig. 2 is a fragmentary transverse section on the line 2:'2 of Fig. 1.. Fig. 3 is a perspective of a. middle plate. Fig. 4: is a fragmentary section taken longitudinally of the car showing in detail a slightly modified form 01": joint.

Thecar body 1 is of the usual type having upright sides 2 and ends 3 and the usual plats beams, or top frames, .4. The roof rests directly 1011 the plate beams. It is composed of rectangular elongated. plates 6 bent on a transverse line t midway of their longest dimension to form the-rid of and give suitable pitch to the roof, and bent down at their ends to torni a facia 21. These plates are to be placedon the car with their longest dimension. extending across the car and joined at their edges to form a continuous rooii Each plate is strengthened by a web, the general direction of whichis parallel to the length of the plate and transverse oi the root. In the preferred ty )e shown in Figs. 1 to 3, this web consists o a flanged girder or T iron placed with a flange or side web on top of the plate extending along one of its long edges; 0., across the ar, and with the web 9 depending. The girder is secured to the plate by means'of rivets 10 passing through the side web. Packing 24, of rubber, or other compressible material, is placed between the girder and the plates. The end plates 11 are provided at their outer edges with a depending flange 12 formed of the web of an angle iron-14,

the other Web, 15, of which isplaced on top of the end. plate and secured thereto by suitahle rivets 16, and front and rear plates 20,

out on the upper edge to conform tothe pitch of the roof, are secured to the flange 12 at each end of the car. The plates forming theroof of each car consist of a set or series. That at one end. is provided with an angle iron 14, described, extending along one edge, and a T iron 8 extending along the opposite and parallel edge. the other end is provided with an angle iron 14.- extending along one edge, the other series, each is provided with a T iron 8 extending along one edge, the other edge being free. The free longitudinal edge of each plate is punched with a line ofrivetholes and the free side Web 17 of each stiliener is punched. with a line of rivet holes adapted to register with those of the plate. i

To set up the roof, a middle plate 18 having a T iron- 8 secured to one longitudinal edge is placed with its free edge 19 under the free side web 17 of the T iron 8 carried therein are brought into registration with the rivet holes of theweb. The rivets are driven and another middle plate is similarly placed withits free edge 19 under the free Web 17 of the T iron carried by thc middle plate 18, and the bperation 15 repeated. The other. end plate 11 which carries no 'l" iron, but has one edge provided with. an angle iron 14 and the other edge free, is placed with its free edge under the web 17 and attached thereto, as previously described. It is obvious that as many middle plates as necessary may be used, dependmg on the length of the car and the width of the plates. A saddle piece 34 may be secured to each stiffening member by bolts 35, as shown. These saddles receive running boards 36. J '1 The operation of setting up the roofas described may be performed on any suitable support, orby placing the plates in position on the car. If the setting up operation is with the tacia flanges 21 and the front and rear plates 20 inclosing the upper portion of the side walls. The roof may be allowed to rest in. this position, held by the force of gravity and limited in its horizontal mo- .tion by the webs 9, the end plates 20, and the facia flanges. lfdeslred, the plates may be unched and secured to the car bygineans of lziolts 22 passing through the plate beams The plate .at

by the end plate 11, and the rivet holes edge being free. Of the other plates of the performed-away from the car, the roof is lifted bodily and placed on the plate beams 4. In the modification o-f'my invention illustated in Fig. a angle irons 30 are substituted for the T irons 8 of Figs. 1, 2 and 3, and the vertical webs turned upward. Suitable packing of rubber, or compressible material, is placed between the angle irons at 31, and between the angle irons and the plates at 32. Vhen the bolts 33 by which the members are secured together are tightened, the packing is compressed and the structure is made waterproof.

Having thus described my invention, what I claim and desire to secure by Letters latentis:

1. As an article of manufacture, a roofing material for cars consisting of substantially rectangular metal plates or strips, each bent to l'or'm a central ridge extending transversely of the plate, and a T iron secured to and extending'along one edge of the plate at right angles to the ridge.

2. As 'an article of manufacture, roofing material for cars consisting of substantially rectangular metal plates or strips, each bent to form a central ridge extending transversely of the plate, and a fianged'beam secured to and extending along one edge of the plate at right; angles to the ridge, the edges of the plate parallel to the ridge and the ends of the flanged beams being deflected to form reinforced flanges.

3. A car roof comprising a set of sheet metal plates placed parallel and extending t 'ansversely of the car, T irons between the plates connecting their edges, each T iron having its side webs on the top of and secured to the adjacent edges of the plates and its middle web between the plates the whole forming a rigid structure.

4'. In a car roof, a set of sheet metal plates placed parallel and extending transversely of the car, T irons between the plates connecting their edges, each T iron having its side webs secured to the adjacent edges of the plates and its central web depending between the plates the whole forming a rigid roof.

5. Ina car root", a set of sheet metal plates placed parallel and extending transversely of the car, T irons connecting the edges of having its side webs secured to the adjacent edges of the plates, and angle irons, each havlng one web dependmg, one such angle -1ron secured to the outer edge of each end plate.

(5. In a car roof, a set of sheet metal plates of the car, .T irons connecting the edges of the plates, each having its side webs secured to the adjacent edges of the plates and its 'eo center web depending between the plates, and an angle iron having one web dependfng secured to the outer edge of each end plate.

7 As a car roof, a set of sheet metal plates placed edge to edge and extending transversely of the car, T irons connecting the adjacent edges, the side webs of the T irons secured to the edges of the plates, the central webs of the T irons upright, and an angle iron having one web depending secured to the outer edge of each end-plate parallel to the T irons.

Spln a *ar roof, the combination of a series of metal plates having parallel edges arranged transversely to the car and bent in the center to form a ridge, a series of T irons arranged between the juxtaposed edges of the plates bent to the same shape as the plates and having the central web depending between the edges of the plates and the lateral webs on top of and secured to the edges of the adjacent plates, thus forming a roof composed of alternate plates and. trusses.

9. In combination with a car body havin the usual plate beams extending along and secured to the tops of the car walls, a rigid root consisting of a set of sheet'metal plates, T irons extending across the car between the plates and secured to the edges of the plates, the plate beams notched and the central webs of the Ts depending and resting in the notches.

10. In combination with a car body havand resting in the notches, the outer edges.

of the plates and the ends of the T irons deflected to form a reinforced flange, and 11 ans securing the flange to the plate beams;
